The lives of all human beings are dependent on clean air. The World Health Organization (WHO) has estimated that 9 out of 10 humans inhale polluted air, which is responsible for 1 out of 9 deaths globally. Air pollution is linked to ~ 9 million premature deaths. Cities are hot spots for air pollution. Urban atmospheric emissions contribute ~50% to 80% of total global greenhouse gas emissions as well as airborne particles or aerosols, including small nanoparticles, and those consisting of manufactured emerging contaminants. Since air is the fastest moving fluid in the Earth's ecosystem, air pollutants (such as nanoparticles) can be transported to remote regions, such as Arctic. This exciting program goals is to address major uncertainties identified by both the Intergovernmental Panel on Climate Change (IPCC) and the WHO: aerosols, with a focus on smaller nanoparticles, physicochemical processes.  The proposed R&D program is building upon the team's recent world-class discoveries, proposing innovative research, which will establish a new niche for Canada in the domain of airborne nanoparticles and emerging contaminants. It is well-aligned with the government of Canada's strategic development plan, including environment, Arctic, urban development, and sustainable technology. The overarching goal of this research program is to better understand the sources and processes controlling the budget of airborne aerosols and emerging nano-contaminants by developing an innovative approach that will integrate physical and analytical chemistry, with modelling and development of technology, in collaboration with network of partners, to create a decision tool that we foresee can  be incorporated into Canadian air quality models, which are currently used for policy making purposes. It will lead to more effective planning of environmental management measures specifically targeted against air pollution.  The specific R&D themes include: (a) advancing the boundaries of understanding of the physicochemical processes involving airborne nanoparticles, focusing on emerging nano-contaminants, and (b) opening a new era of sustainable technology for atmospheric observation and air pollution remediation. Our objectives will be addressed using a complementary observational, experimental and modelling as well as technology development approach.  This team has the savoir-faire, world-class expertise, cutting edge facilities, to address these important objectives effectively.  We believe that this program is of medium risk and of very high impact potential. This program will conduce a formidable and stimulating multidisciplinary environment to ensure access to state-of-the-art facilities and world-class training of 18 bright HQP per year. These young scientists will obtain their career of their choice to make significant contributions to the Canadian society. They will become future leaders in academia, governmental, industrial, and NGOs, all former ream alumni achieved.

所有人类的生活取决于清洁的空气。世界卫生组织（WHO）估计，在10人中，有9个被污染的空气，这是全球9例死亡中有1人。空气污染与约900万人死亡有关。城市是空气污染的热点。城市大气排放量占全球总温室气体排放的约50％至80％，以及空气中的颗粒或气溶胶，包括小纳米颗粒，以及由制造的新兴污染物组成的颗粒。由于空气是地球生态系统中移动最快的流体，因此空气污染物（例如纳米颗粒）可以运输到偏远地区，例如北极。这个令人兴奋的计划目标是解决政府间气候变化（IPCC）和WHO：Aerosols识别的主要不确定性，重点是较小的纳米粒子，物理过程。拟议的研发计划基于该团队最近的世界一流发现，提出了创新的研究，该研究将在空中纳米颗粒和新兴污染物的领域为加拿大建立新的利基市场。它与加拿大政府的战略发展计划（包括环境，北极，城市发展和可持续技术）保持一致。该研究计划的总体目标是通过开发一种创新的方法，可以更好地了解机载气溶胶和新兴的纳米 - 抗激素预算的来源和流程，该方法将将物理和分析化学的创新方法与技术建模和分析化学整合在一起，并与伙伴的合作建立与网络合作，以创建我们可以将我们预见到的策略的决策工具，从而将目前的策略纳入Canad Air质量，该策略是将其纳入Canad Air质量的。这将导致针对空气污染的专门针对的环境管理措施的更有效的计划。特定的研发主题包括：（a）提高对空气纳米颗粒涉及的物理过程的理解的界限，重点关注新兴的纳米 - 抗激素，以及（b）为大气观察和空气污染修复开设可持续技术的新时代。我们的目标将使用完整的观察，实验和建模以及技术开发方法来解决。该团队拥有Savoir-Faire，世界一流的专业知识，最先进的设施，以有效地解决这些重要目标。我们认为，该计划具有中等风险，具有很高的影响力。该计划将进行强大而刺激的多学科环境，以确保获得最先进的设施和每年18个Bright HQP的世界一流培训。这些年轻的科学家将获得他们选择的职业，为加拿大社会做出重大贡献。他们将成为所有前REAM校友的学术界，政府，工业和非政府组织的未来领导者。
